I've watched the three Bears preseason games on tape replay on NFL Network. There are things to worry about, but they should get ironed out.
First, the special teams have been absolutely horrible. Poor snaps on punts/kicks, missed field goals, missed tackles, poor returns, bad punts, etc. I have confidence that all of those will get worked out as the special teams players get locked in and the season starts.
Second, the offense has been anemic. There are some concerns about the O-line, but I am still fairly confident that that unit will be OK. Chris Williams struggled against the Raiders a couple of weeks ago, but he should be a great LT for the next decade. He showed great signs last year and I expect him to be OK. Working against Peppers during the pre-season should help. Louis (RG) and Omiyale (RT) are new starters and Garza moved from RG to LG. So, the unit is all new and needs some games to get it together. I like the line.
I believe the receiving corps will be solid, but you can see that timing is not there yet. There are some passes that Cutler is just off on or the receivers are a step behind. Hopefully that will get going.
The running game should be better and I like the pickup of Chester Taylor. Forte ripped off an 89 yard run against the Raiders and he looks much faster. Knee and ankle injuries really slowed him down last year, but he looks like a different guy. I think he is set for a big year.
The big question is whether Cutler can avoid the costly mistakes. We'll see.
The D has been much better, but unfortunately, they haven't played with their whole first unit because of dings this pre-season. Chris Harris at strong safety has been a solid tackler, but he has missed a couple of angles on passes and given up big plays. Safety play has been a concern for a couple of years and I hope to see improvement there. I think Peppers will have a huge year and I expect this to be a solid defensive unit.
The problem is the Packers look great right now. I'll make my predictions right before the season.
